Detailed ways

Exemplary aspects of the invention shown in the drawings will now be described in detail. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

Figure 1 shows a telecommunications/telecommunication connection cabinet 100 that may be installed, for example, on a plinth or in other areas where it is desired to provide fiber optic connectivity to users. The telecommunications connection cabinet 100 provides a location for external equipment fiber optic cables to be connected to fiber optic distribution cables. The distribution cables are then routed to customer equipment to provide fiber optic service and connectivity at the customer location. A typical configuration for servicing subscribers may include splitting the signal from an outside plant (OSP) cable with a splitter into multiple distribution cables, each distribution cable providing a connection to a particular subscriber facility. In a two-way communication configuration, a common splitter might split the optical signal in an OSP cable into 32 separate signals and combine these 32 signals into the OSP cable. The telecommunications connection cabinet 100 is similar in nature to that of commonly owned U.S. Patent Application No. 10/613,764, filed July 2, 2003, entitled "Communications Connection Cabinet," the disclosure of which is incorporated herein as refer to.

A plurality of cables 108 connected to user equipment may be routed into the communication connection cabinet 100 . One or more OSP cables 106 may be directed into the telecommunications connection cabinet 100 and to a splice, such as a splice tray or panel 110 . OSP cable 106 may be spliced into second cable 104 in splice panel 110 . The second cable 104 is routed from the splice panel 110 to the first cable management structure 112 and to the splitter 102 in the splitter installation area 103 . Splitter 102 splits the optical signal transmitted over OSP cable 106 and second cable 104 into up to 32 signals, which are directed into an equal number of fiber optic distribution cables 114 . Cables 114 are directed from splitter 102 through cable management area 112 and into a second cable management and spare storage area 116 , which includes a plurality of spare cable storage spools 117 . From spare storage area 116 , cables 114 may be directed to connector racks in excess cable storage area 118 or adapters in adapter array 120 . Each of these cables 114 is preferably terminated by a fiber optic connector (with a fiber optic connector at its end).

In excess cable storage area 118 , a plurality of connector brackets 122 are mounted in mounting slots in bulkhead 124 . Connector bracket 122 (described in further detail below) includes a plurality of openings for receiving and releasably retaining fiber optic connectors. The openings in the connector holder 122 preferably do not provide a continuous optical path, but instead accommodate and protect the polished end faces of the optical fibers in each cable 114 that is mounted to a terminal fiber optic connector. This protection may be provided in conjunction with end caps as shown in commonly owned U.S. Patent Application No. 10/610,325, filed June 30, 2003, entitled "Fiber Optic Connector Brackets and Methods" , the disclosure of which is incorporated herein by reference. Alternatively, the connector bracket 122 may surround and protect the polished end face of the connector-terminated cable 114 without the need for a protective end cap.

In adapter array 120 , a plurality of fiber optic adapters 123 are installed to receive connector-terminated cables 114 . The connector of the cable 114 is received in an opening on the front side of the adapter 123 . The adapter 123 also includes an opening on the opposite rear side adapted to receive one of the user equipment cables 108 , a connector-terminated cable. Adapter 123 in adapter array 120 may optically connect one of cables 114 to one of cables 108 for transmitting optical signals from OSP cable 106 to a user device connected to that cable 108 . Such cable termination connectors and adapters 123 are known in the industry. As shown in Figure 1, the connector is an SC connector, and it is contemplated that other types, formats, forms and sizes of communication connectors may be used.

The telecommunications connection cabinet 100 includes a front 126, a pair of opposing sides 128, a rear wall 130, a bottom 132 and a top 134, all of which cooperate to define an interior cavity 136 in which the various components described above are mounted. . These components are accessible through an opening 140 in the front 126 which can be closed by a pair of doors 138 .

Referring now to FIG. 2 , an alternate embodiment telecommunications connection cabinet 200 includes the same components as telecommunications connection cabinet 100 . The appearance or location of some components is changed, but the functional characteristics are similar to the communication connection cabinet 100 . The telecommunications connection cabinet 100 includes a pair of adapter array panels 121 , each panel 121 including a total of four rows of 18 adapters 123 , or 72 adapters 123 in each row. The telecommunications connection cabinet 200 includes three such adapter array boards for a total of 216 adapters 123 . The telecommunications connection cabinets 100 and 200 each include a single bulkhead 124 located in the excess cable storage area 118 . Each bulkhead 124 includes openings for mounting three rows of three connector brackets 122 . Each connector bracket 122 includes a total of 8 openings for receiving, storing and securing the 8 cable connectors of the cables 114, providing a total storage capacity of up to 72 connectors.

Referring now to FIG. 3 , the bulkhead 224 is shown having nine openings 226 in a front 228 including a rear surface 229 , and a connector bracket 122 is positioned in one of the openings 226 . A pair of opposing side walls 230 extend rearwardly from opposite ends of the front face 228 to a pair of mounting flanges 232 . Mounting flange 232 includes fastener openings 234 for mounting bulkhead 224 to one of telecommunication connection cabinets 100 or 200 or a similarly configured telecommunication connection cabinet. The bulkhead 224 is similar to the bulkhead 124 of FIGS. 1 and 2, except that it is configured so that the front face 228 slopes toward the side of the telecommunications connection cabinet in which the bulkhead 224 is installed. Angle adjustment of bulkheads including means for receiving fiber optic connectors is known in the industry and may provide, among other advantages, improved cable management and packing density while facilitating bend radius protection. As shown above in FIGS. 1 and 2 , the bulkhead 124 has side walls 230 of equal length so that the bulkhead 124 does not slope to either side of the telecommunications connection cabinet 100 or 200 .

Each opening 226 includes a first or top end 227 and a second or bottom end 225 . A pair of ears 236 are disposed on each of a pair of opposing sides extending from the top end 227 to the bottom end 225, the ears 226 cooperating with keying features 238 on the connector bracket 122 to orient the connector in the opening 226 Bracket 122. The connector bracket 122 includes a releasable latch 240 at one end and a protrusion 242 at the opposite end (as shown in FIGS. The connector bracket 122 is retained in the opening 226 . It is desirable to control the direction of the force that may be exerted on the connector bracket 122 by tension in the cable 114 to prevent accidental release of the connector bracket 122 from the opening 226 . Keying features 238 and ears 236 cooperate to ensure that connector bracket 122 is properly oriented in opening 226 to resist accidental release through such cable tension.

Openings 226 in front face 228 of bulkhead 224 (and bulkhead 124 ) are sized to receive up to eight adapters 123 when connector bracket 122 is not in place. This allows bulkheads 124 and 224 to provide additional space for optical connection cables 114 and user equipment cables 108 to increase the connection capacity of communication connection cabinets 100 and 200 and similarly configured cabinets.

Referring now to FIGS. 4-13 , the connector bracket 122 includes a housing 160 having eight openings 150 for receiving and releasably retaining the connectors of the cables 114 . As noted above, the cable 114 is terminated by (or terminated with) an SC-type connector, and the opening 150 is configured to receive and releasably retain the SC connector. As shown in FIGS. 4 to 6 , openings 150 extend through housing 160 from front 162 to back 164 , and each opening 150 can receive a connector of cable 114 in the finish of the optical fiber held by cable 114 and the connector. There is a dust cover near the end face. Such dust caps are shown in the above cited and incorporated US patent applications. Alternatively, the opening 150 may be closed at the ends, thus preventing contamination of the polished end face of the connector with or without a dust cap.

Housing 160 includes a first end or top 152 and a second end or bottom 154 . A releasable latch 240 is mounted to the top 152 and a protrusion 242 is located in the bottom 154 . Rail 156 extends along side 166 of housing 160 between top 152 and bottom 154 . The keying member 238 is positioned along the rail 156 and extends beyond the back 158 of the rail 156 . A portion of housing 160 that extends beyond rear face 158 of rail 156 is sized to fit within opening 226 . When inserted into opening 226 , back 158 of rail 156 engages front 228 and keying member 238 engages one of ears 236 to properly orient top 152 and bottom 154 of housing 160 .

To insert housing 160 into opening 226 , base 154 is first positioned in opening 226 by front face 228 such that locking face 243 of protrusion 242 is behind front face 228 at bottom end 225 and engages rear surface 229 of front face 228 . Top 152 is then inserted into opening 226 . The sloped surface 244 of the releasable latch 240 engages the top end 227 of the opening 226 and deflects to allow the sloped surface 244 and the locking surface 241 of the releasable latch 240 to pass through the opening 226 . The locking surface 241 of the releasable latch 240 engages the rear surface 229 . Opposite the locking faces 241 and 243 is the back face 158 of the rail 156 which engages the front face 228 . The keying member 238 engages the ear 236 of the opening 226 . The releasable latch 240 includes a finger tab 246 that can be depressed to retract the locking surface 241 to disengage the locking surface 241 from the rear surface 229 and allow the housing 160 to be removed from the opening 226 . Housing 160 is configured to be inserted through front face 228 of bulkhead 124 or 224 when telecommunications connection cabinet 100 or 200 is accessed through opening 140 in front portion 126 .

Referring now to FIGS. 7-13 , the housing 160 of the connector bracket 122 includes an orientation slot 170 and a latch arm 168 in each opening 150 . Latch arm 168 cooperates with the latch feature of the SC size adapter to allow such connector to be releasably retained in opening 150 . For other models and types of connectors, different latch features may be included in opening 150 to allow these connectors to be releasably retained. Orientation slot 170 may cooperate with an orientation feature on the exterior of the SC connectors to orient all connectors in opening 150 in the same manner. This orientation of the connector is not necessary for SC connectors, which typically have symmetrical latch features, but for other connectors it may be desirable to have a different latch structure.

Referring now to FIG. 14 , the splitter 102 includes a housing 172 having a cable inlet 174 for the second cable 104 and a pair of cable outlets 176 for the cable 114 . As shown, each cable outlet 176 allows up to sixteen cables 114 to exit the housing 172 . Terminating each cable 114 is a connector 180 having a polished end face 182, shown as an SC connector. Other sizes and arrangements of cable outlets are also contemplated. Different numbers of cables 114 may exit from housing 172, depending on the connection requirements and the arrangement of the optical splitters in splitter 102 to be met. A releasable latch 178 is mounted to one side of the housing 172 to retain the splitter 102 in the splitter mounting area 103 of the telecommunications connection cabinet 100 or 200 or a similarly configured telecommunications connection cabinet.

FIG. 14A shows a fiber optic device module 202 that is similar in layout to the splitter 102 with the second cable 104 and the plurality of cables 114 . The second cable 104 may be a single harness cable, and the module 202 may include a splitter connected to the connector cable 104 and the cable 114 , such as described above with respect to the module 102 . Alternatively, the cable 104 may be a multi-strand bundle cable, and the module 202 may only serve as a fanout module that separates the bundle into cables 114 . Each cable 114 is terminated by a connector 180 that is each inserted into the connector bracket 122 . Such a module 202 may be used in the method for increasing connection capacity described below.

A method of increasing the connection capacity of the telecommunications connection cabinet 100 may include installing a pre-configured splitter 102 in combination with one or more connector brackets 122 . It is desirable to provide easy field expansion of connection capacity in the telecommunications connection cabinet 100 so that the telecommunications connection cabinet 100 does not need to predict the final connection configuration for a particular customer service area when installed. The telecommunications connection cabinet 100 can be installed with just enough connection capacity to service the current needs foreseen for the user area and allow for incremental expansion as more connections are required in the area. The following method of increasing the connection capacity of the telecommunications link cabinet 100 is also applicable to the telecommunications connection cabinet 200, and can be used to initially construct the telecommunications connection cabinet 100 before installation or to expand the capacity of the telecommunications connection cabinet 100 on site.

In order to increase the connection capacity in the communication connection cabinet 100 , a splitter 102 is used, which is pre-configured with cables 104 and 32 cables 114 terminated by connectors 180 . The splitter 102 is installed in the splitter installation area 103 and the free ends of the cables 104 are guided into the cable management structure 112 and to the splice panel 110 . The free end of the cable 104 is spliced into one end of the OSP cable 106 in the splice panel 110 . The splice optically connects OSP cable 106 to each cable 114 . The connectors 180 for the cables 114 are pre-inserted into the four connector brackets 122 . The cables 114 are routed from the splitter 102 through the cable management structure 112 to the second cable management structure 116, where excess cable lengths may be retained in a spare cable storage device. Since the splitter 102 can be pre-configured for different communication connection cabinets as well as the communication connection cabinet 100, the length of the cable 114 of the splitter can be longer than the required length of the communication connection cabinet 100, and the excess length section can be kept in reserve. The cable is stored near the spool 117 (see Figure 1).

From the second cable management area 116 , the cables 114 and the connector bracket 122 with plug-in connectors 180 are positioned in the excess cable storage area 118 . Each connector bracket 122 simply snaps into one of the openings 226 of the bulkhead 124 . The addition of additional connection capacity is now complete. When a user connection is required, the user equipment cable 108 is routed into the communication connection cabinet 100 and terminated by a connector 180 . The connector is inserted into the rear opening of the adapter 123 in the adapter array 120 . Alternatively, when telecommunications connection cabinet 100 is installed, all adapters 123 in adapters 122 may have pre-wired customer equipment cables 108 on the back and these cables are routed to the customer's premises according to projected future customer wiring. When such a pre-wired user requires an actual connection, the cable 114 need only be plugged into the front of the appropriate adapter 123 . One of the cables 114 in the excess cable storage area 118 is selected and its connector 180 is removed from the connector bracket 118 . Selected cables 114 are rerouted in second cable management area 116 as needed to provide the desired cable length and connectors 180 are plugged into appropriate adapters 123 in adapter array 120 . If the connector 180 of the selected cable 114 includes a dust cap to protect the polished end faces of the optical fibers, the dust cap is removed prior to insertion into the adapter 123 .

The splitter 102 includes 32 cables 114 and connectors 180 that are inserted into the four connector brackets 122 when the splitter 102 is installed. When the cables 114 and connectors 180 are transferred into the adapter array 120 , some or all of the connector racks 122 may be empty of all the connectors 180 . At this point, the empty connector rack 122 may be removed from the excess cable storage area 118 and discarded or recycled. Removal of these empty connector brackets 122 will free the openings 226 in the bulkhead 124 to allow the connector brackets of additional splitters 102 to be installed and more capacity to be added to the telecommunications connection cabinet 100 .

The connector 180 of the appropriate cable 114 can be removed from the adapter 123 if the connection to the user equipment needs to be terminated. The cables 114 are then rerouted in the cable management structure 116 and the connectors 180 are inserted into the openings 150 of the connector brackets 122 in the excess cable storage area 118 .

The splitter installation area 103 of the communication link cabinet 100 includes space for installing up to four splitters 102 , while the communication link cabinet 200 provides space for installing up to eight splitters 102 . With this configuration, the communication connection cabinet 100 has the connection capacity to separate each of up to four OSP cables into 32 cables 114 , or a total of 128 cables 114 . In adapter array 120 there are a sufficient number of adapters 123 to allow each of these cables 114 to be connected to a corresponding user equipment cable 108 .

However, the communication connection cabinet 200 has the connection capacity to separate each of up to eight OSP cables into 32 cables 114 , or a total of 256 cables 114 . Adapter array 120 in telecommunications connection cabinet 200 provides only a total of 216 adapters 123 for receiving connectors from cables 114 . Once the adapter array 120 has been completely populated with cables 114 , there may be as many as 40 excess cables 114 in the excess cable storage area 118 which is not provided with adapters 123 for connection to user equipment cables 108 .

As shown in FIGS. 4-13 , the housing 160 of the connector holder 122 having eight openings 150 generally has the same footprint as an array of eight adapters 123 . When adapter array 120 has been completely populated with cables 114 from splitter 102 , connector brackets 122 may be removed from openings 226 in bulkhead 124 and up to eight adapters 123 may be positioned in each opening 226 . By completely filling the 5 openings in bulkhead 124 with adapters 123, an additional 40 cables 114 can be connected to subscriber equipment cables 108, effectively increasing the capacity of adapter array 120 so that 40 excess cables 114 can be utilized. Even though five openings 226 are used by the adapter 123, there are still openings 226 for the connector bracket 122, so that the cable 114 can be stored when the connection to the user equipment cable is removed or changed.

FIG. 15 shows a third alternative embodiment telecommunications connection cabinet 300 having a similar construction to telecommunications connection cabinets 100 and 200 , but including bulkheads 224 located in excess cable storage area 118 . Adapter panel 121 and bulkhead 224 are angled toward cable management structure and backup storage 116 to improve transfer of cables 114 from cable management structure 116 to adapter 123 and connector bracket 122 . In addition, cable supports 302 are disposed on the panel 121 and the bulkhead 224 to provide support for the cables 114 extending to the adapter 123 and the connector bracket 122 , respectively.

Fig. 16 shows a communication connection cabinet 400 according to a fourth embodiment of the present invention. The communication connection cabinet 400 is similar in construction to the communication connection cabinets 100, 200 and 300 previously described and has a cable management structure 416 with spare cable storage and excess cable storage along both sides of the adapter array 120 Area 118. The adapters 123 adjacent to the left side of the panel 121 are inclined toward the left side of the communication connection cabinet 400, and the adapters 123 adjacent to the right side of the panel 121 are inclined toward the right side of the communication connection cabinet.

Figure 17 is a telecommunications connection cabinet 500 of a fifth embodiment including a side-by-side structure 502 in the telecommunications connection cabinet. Each structure 502 is similar in construction to telecommunications connection cabinet 400 .

FIG. 18 is a telecommunications connection cabinet 600 of a sixth embodiment in which the excess cable storage area 118 is positioned alongside one of the interior walls 602 . FIG. 19 shows bulkhead 604 including a plurality of openings 226 for receiving connector bracket 122 . Other elements in the communication connection cabinet 600 are similar to the communication connection cabinets described above. The bulkhead 604 includes a pair of mounting flanges 606 and 608 for attachment to the inner wall 602 and the cabinet rear wall 130, respectively. The above specification, examples and data provide a complete description of the manufacture and use of the invention. Since many embodiments of the invention can be made without departing from the spirit and scope of the invention, the invention resides in the claims hereinafter appended.
